Cosworth has rejoined the 24 Hours of Le Mans as a powertrain supplier, marking its first engine entry at the race since 2015. Alongside its expanded role, the company provides electronic components across all Le Mans classes, maintaining a presence on 85% of the grid.
A Hypercar entry is powered by a race-optimised version of Cosworth’s 6.5-litre naturally-aspirated V12 engine. Originally developed with an automotive manufacturer for a high-performance road car, it has been refined to meet Balance of Performance regulations while retaining its characteristic sound and power delivery.
Beyond the powertrain, Cosworth supplies advanced electronics such as the Antares 8 ECU and Centaurus 5 power distribution system, reinforcing its position in endurance racing technology.
Dr. Florian Kamelger, Cosworth CEO, stated: "Cosworth's return to Le Mans as a power unit supplier marks a significant milestone in our company's history. This partnership brings together engineering excellence with a shared passion for performance, precision, and innovation. This hypercar project represents everything Cosworth stands for -- engineering excellence, cutting-edge technology, and the relentless pursuit of perfection."
Bruce Wood, Managing Director of Powertrain at Cosworth, commented: "This is a momentous year for Cosworth, as we return to the pinnacle of sports car racing as an engine supplier, supporting a leading manufacturer in its quest for Le Mans glory. This year marks the culmination of a decade of collaboration, and we cannot wait to see and hear the roar of our V12 engine at race tracks across the world."
Cosworth has a long history at Le Mans, with its DFV engine securing victories in 1975 and 1980. The company has also played a pivotal role in Formula 1, recording 155 Grand Prix wins between 1967 and 1983.
Currently, Cosworth supplies electronic components across multiple Le Mans categories, including LMDh, LMP2, and LMGT3.
